Hi Semy:
The more elegant solution is to use gmetad-python and write plugins to
manipulate the metric data collected however way you want. For more
information, please see the README:
https://github.com/ganglia/monitor-core/blob/master/gmetad-python/README
And Peter is right, ganglia-general is
TCP is not supported. Ganglia's binary protocol and sFlow both use UDP. Loosing
a packet is no big deal - a new measurement will be sent next polling interval
and the benefits of a stateless protocol are considerable.

Btw. sFlow can use TCP as well as UDP? I'm worr

It could definitely help even if I'm not good at PHP. I'll try it. Thx.

gweb allows downloading RRD data as either csv or json. Might that help?

I think I've found answer for my question. I've just read few files from
source code of ganglia-web and as i can see they are reading RRD to draw
everything so i think I have to write my own wrapper around RRD to do what
i need. Anyway thx for informations.
Cheers,

There are people on this list who should be able to answer questions relating
to gmetad (although you might have better luck on the ganglia-general list). My
expertise is limited to sFlow.

In next 2-5 days I'll try ganglia + sFlow again, so I'll definitely let you
know about my problems.
If you can't answer my previous question to whom should I send it?
Cheers,

I can't help you with your questions about gmetad, but I would be very
interested in hearing where you ran into trouble during the sFlow/Ganglia
configuration. I am currently working on documentation and would like to make
sure that I fill any gaps.

I've already seen sFlow and ganglia about month ago, and I had some
problems during configuration, but maybe I should try it again.
So maybe I have different question now. Is there any way to query gmetad
about historical data? I'd like to retrieve some data in my external piece

Simon,
Ganglia 3.2+ can collect and display sFlow metrics:

You can monitor the virtual machines by installing Host sFlow agents
